175167-55-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 175167-55-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,5,1,6 and 7 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 175167-55:
(8*1)+(7*7)+(6*5)+(5*1)+(4*6)+(3*7)+(2*5)+(1*5)=152
152 % 10 = 2
So 175167-55-2 is a valid CAS Registry Number.

An improved procedure for the synthesis of chiral 2-aza-bicyclo[2.2.1]heptane
Chiu, Charles K.-F.
, p. 577 - 584 (2007/10/03)
Grieco's protocol for the synthesis of 2-aza-bicyclo[2.2.1]heptane is modified and adapted for large scale preparation. The optical purity of the material is readily upgraded by purification through a chiral salt.
